IMPROVEMENT IN CAR-WINDOWS.

' Specification forming part of Letters Patent No. 180,158, dated July25, 1876; application filed September 25, 1875.

' of Chicago, in the county of Cook and State of Illinois, have inventeda Oar-Window, of which the following is a specification, reference beinghad to the accompanying drawings, which form a part hereof.

My invention relates to that class of carwindows which have two sashes,one above the other.

My invention consists in the combination of the window-casement and thewire screen, so arranged that the wire screen will slide into the wallabove the window-frame and down to the top of the lower sash and also inmaking the window casement and the top sash of the window in such mannerthat the top sash will slide up into the wall above the window.

This construction enables me to open the top half of the window and drawdown the wire 1 screen, and admit air to the car and exclude thecinders, &c.'

My invention further consists in attaching the curtain to the bottom ofthe frame of the wire screen, so that the curtain, when the wire screenis down to admit the air, can be used for the lower part of the Windowonly, and when the wire screen is raised into the wall the curtain canbe used for the entire window.

In the accompanying drawings, Figure 1 represents afront view of myinvention 5 F ig. 2, a transverse vertical section thereof, taken at theline at a: in Fig. 1.

A represents the window-casement. B represents a recess above thewindow, made sutficicntly large to receive the wire screen and the upperwindow-sash. O is the lower window-sash. D is the upper window-sash, andE is the screen. F is the window-curtain, attached with the ordinarycurtain-fixtures to the lower part of the frame of the wire screen.

When it is desired to admit air into the car the upper window-sash D israised into the recess B above the window, as shown in Fig. 2, and thewire screen is pulled down from the recess to the position shown in thedrawings. The curtain F can then be used for the lower part of thewindow.

' When it is desired to close the window the wire screen is raised intothe recess B, and

the upper window-sash D is pulled down, which tightly closes the top ofthe window.

The curtain then extends from the top of the window, and can be used forthe entire window.

G is the ordinary window-cornice, under which the top of the curtainpasses when the wire screen is raised.

It is very desirable to admit air to a car or building, and at the samecover the aperture (which you open for the admission of air) with a wirescreen, to exclude as much as possible dust. cinders, insects, 800. Itis also desirable to have the wire screen as convenient as possible forapplication, and at the same time be entirely out of sight, and leavethe window with. the ordinary appearance when not in use. I accomplishall this by making the recess B above the window-casement,'into whichthe wire screen can be raised entirely out of sight when itis notdesiredfor use, leaving the window with the sameappearance as any ordinarywindow.

All that is required to get ventilation is to open a window and pulldown the wire screen into the position shown in the drawings.

By attaching the curtain to the lower part of the screen it is alwayskept in front of the window, where it is wanted, but never in front ofthe screen, where it is not wanted.

I claim 1, The combination, substantially as specitied, of thewindow-casement A, recess B, screen E, and curtain F, attached to thelower .end of the screen.

scribed, of the window-casement A, recess B, upper sash D, and screen E,havingthe curtain F attached to its lower end.

3. The combination, substantially as described, of the window-casementA, the recess B, andthe upper and lower sashes -O D, so

constructed and arranged that the upper sash can be raised into therecess, but the lower one cannot. ALBERT B. PULLMAN. Witnesses:
